If Harry Potter became a Green Lantern in fanfiction, his character would undergo a significant transformation. He would no longer be just the 'Boy Who Lived' in the context of the wizarding world. His identity would be intertwined with that of a Green Lantern. He would have to learn to control the power of the ring, which would require discipline. This newfound discipline might spill over into his other aspects of life. He would be more responsible and less impulsive. His relationships would also change. His friends might look at him in a new light, and he would attract new friends from the Green Lantern Corps. His sense of justice, which was already strong, would be further refined and expanded to cover the entire cosmos.
He would become more confident in his abilities. The Green Lantern ring gives its wielder a sense of power and purpose. Harry, who has always had self - doubts, would grow into a more self - assured person.
Naruto's character would gain a new sense of responsibility. As a Green Lantern, he'd have to abide by the Corps' rules and uphold justice on a much larger scale. This might make him more serious at times, but his core of being a fun - loving and determined person would still remain. He'd also learn to work in a team with other Green Lanterns, which could be different from his experience with his ninja teams as they come from diverse backgrounds.
He would become much more aggressive. Harry is usually a calm and strategic fighter, but as the Hulk, he would rely more on brute force and his first instinct would be to attack rather than think through a plan.
He would become more fearless. Riding a dragon requires a lot of courage. Harry, who was already brave, would be even more so. He would be more confident in taking on difficult challenges, knowing he has a dragon by his side.
Harry would be more altruistic. His actions would be guided by the principles of equality and fairness for all. He might give up some of his personal possessions or privileges if it means helping those in need. For example, he could share his knowledge of advanced magic with students from less - privileged backgrounds. Also, he would be more vocal about social injustices, like the discrimination against Muggle - borns or half - bloods, and actively work to change those situations.
He would become more disciplined. As a police, he has to follow rules and regulations, which is different from his rather free - wheeling adventures in the wizarding world. He'd also be more patient, as police work often involves a lot of waiting and surveillance.
His already positive personality would become even more so. He'd be like a beacon of hope. He might be more focused on bringing out the best in others, since that's what Blue Lanterns do.
Naruto's personality would adapt to fit the new role. His existing positive traits like his courage and his ability to make friends would help him in the Green Lantern Corps. He'd be more of a team player perhaps, learning to work with beings from all over the universe. His impulsive nature might still be there, but he'd learn to control it better with the discipline that comes with being a Green Lantern. And his overall goal would shift from becoming Hokage to being a great Green Lantern and protecting the cosmos.
If Harry Potter becomes part of a Pokemon fanfiction, his life would change in many ways. Firstly, his daily routine would be different. Instead of going to magic classes, he'd be out in the wild looking for Pokemon. His friends might also change as he'd befriend other Pokemon trainers. His relationship with magic might even be affected. He could start using magic in new ways related to Pokemon, like using spells to communicate with them. And his sense of adventure would be redirected towards exploring the different regions in the Pokemon world.
He might become more authoritative. Since he has the power of an emperor, he would need to make tough decisions and be more assertive in his commands.
When Harry Potter becomes a god in fanfiction, his relationships would experience a huge shift. His friends would look at him in a new light. Hermione might see him as a being to learn from, constantly asking him about the deeper secrets of magic. His relationship with the Hogwarts faculty would be more of an equal - to - equal among gods, if we consider them as powerful wizards. And his connection to the wizarding community as a whole would turn into a sort of benevolent guardian - like relationship, where they all look up to him for guidance and protection.
